Balouch S, et al. – In this study, researchers explored the associations between loneliness, social networks (social measures), and cognitive and psychopathology decline in people with Alzheimer's disease (AD). Upon recruiting and evaluating 93 participants with mild-to-moderate AD from memory clinics, they concluded that sustaining or creating a network of close friends is beneficial for cognition in this population. On the other hand, greater dementia severity may result in fewer friends.
